(1) The Director of the Department of Transportation or the official of the department designated by the director, upon application and for good cause being shown therefor, may issue a permit in writing authorizing the applicant to operate or move upon the state's public roads a vehicle or combination of no more than two vehicles and loads whose weight, width, length, or height, or combination thereof, exceeds the maximum limit specified by law; provided, that the load transported by such vehicle or vehicles is of such nature that it is a unit which cannot be readily dismantled or separated; provided, however, that bulldozers and similar construction equipment shall not be deemed readily separable for purposes of this chapter; and further provided, that no permit shall be issued to any vehicle whose operation upon the public roads of this state threatens to unduly damage a road or any appurtenances thereto.
(2) Permits may be issued on application to the department to persons, firms, or corporations. The director shall adopt reasonable rules which are necessary or desirable governing the issuance of the permits; provided, that the rules shall not conflict with this title and other provisions of law.
(3) The original copy of every permit shall be carried in the vehicle itself and shall be open to inspection by any law enforcement officer or authorized agent of the department.
(4) The application for any permit shall specifically describe the type of permit applied for, as described in subsection (b), and the application for a single trip permit, in addition, shall describe the points of departure and destination.
(5) The director or the official of the department designated by the director may withhold such permit or, if such permit is issued, may establish seasonal or other time limitations within which the vehicles described may be operated on the public road indicated, or may otherwise limit or prescribe conditions of operation of such vehicle, when necessary to assure against undue damage to the road foundation, surfaces, or bridge structures, and require such undertaking or other security as may be deemed necessary to compensate the state for any injury to any roadway or bridge structure.
(6) For just cause, including, but not limited to, repeated and consistent past violations, the director or an official of the department designated by the director may refuse to issue, or may cancel, suspend, or revoke, the permit of an applicant or permittee.
(b) Duration and limits of permits; bond or insurance requirements.
(1)a. ANNUAL. The director or the official of the department designated by the director, pursuant to this section, may issue an annual permit which shall permit the vehicle or combination vehicle and load to be operated on the state highway system of this state for 12 months from the date the permit is issued, even though the vehicle or its load exceeds the maximum limits specified in this article; provided, that an annual permit shall not authorize the operation of a vehicle including all enforcement tolerances:
1. Whose total gross weight exceeds 150,000 pounds; provided, that gross weights over 100,000 pounds shall require advance routing by the department;
2. Whose single axle weight exceeds 22,000 pounds;
